Sorry guys - I meant the fan (or blower, if that's the proper term)
for the interior heat and a/c.
I'll have to ask her about switching it to the highest speed and see
if that works. Using that logic, would the resistor's function then
be to resist the amount of power that flows to the fan/blower,
allowing the driver to control the speed at which the fan/blower
My weak attempt at deductive reasoning...
